Si je désactive l'obscurcissement , l'application fonctionne bien. Pourriez-vous me dire ce qui se passe?

Answer 1

L'erreur est dans SystemServiceManager.java de Holoeverywhere. Si vous lisez le code vous remarqué qu'il est de lancer intentionnellement l'erreur que quelque chose va mal avec annotations

public static void register(Class<? extends SystemServiceCreator<?>> clazz) { 
    if (!clazz.isAnnotationPresent(SystemService.class)) { 
     throw new RuntimeException(
       "SystemServiceCreator must be implement SystemService"); 
    } 
    SystemService systemService = clazz.getAnnotation(SystemService.class); 
    final String name = systemService.value(); 
    if (name == null || name.length() == 0) { 
     throw new RuntimeException("SystemService has incorrect name"); 
    } 
    MAP.put(name, clazz); 
} 

Une vérification de la proguard troubleshooting document montre que par défaut, il supprime les annotations sauf si vous ajoutez ce

-keepattributes *Annotation*
